What pressure is required for LDH testing?

The required pressure for LDH (Large Diameter Hose) testing is traditionally set at 150 psi. This pressure is established as a standard for evaluating the performance and integrity of large diameter hose under operational conditions. Testing at this pressure allows firefighters to determine if the hose can withstand the working pressures it might encounter in actual firefighting scenarios, ensuring safety and reliability when deployed in the field.

By subjecting the hose to a pressure of 150 psi, it simulates conditions that are realistic yet challenging, which helps in identifying any weaknesses or potential failures in the hose material or construction. This testing process is crucial for maintaining high standards of equipment quality and operational readiness within the fire department.
